Why men's socks shrink and what to do

Short answer: Bamboo socks for men usually shrink because they have been washed or dried too hot and too hard. The fibres pull together, and the sock fits tighter than before. Here is how to wash them so they keep their size, and what you can do if the damage is done.

What makes socks shrink

Socks shrink when heat, moisture and movement make the fibres pull together. It mostly happens in a hot wash or in the tumble dryer on a high programme. Knitted fabric is also elastic and can lose its shape if it is treated roughly. Small changes in how you wash often make a big difference.

Wash socks according to the label

The label in the sock tells you which temperature and programme suit it. Follow it and choose a low temperature rather than a high one. Turn the socks inside out and wash them with similar clothes. Socks for men keep their shape best when they are not exposed to heat.

Drying matters most

The tumble dryer is often the biggest reason socks become too small. Let the socks air dry, lying flat or hanging, away from radiators and direct sun. If you use the tumble dryer, choose a gentle programme with low heat. That way the socks keep both size and softness.

Bamboo socks for men and viscose

Bamboo socks for men are made from viscose from bamboo, and viscose can be more sensitive to heat and moisture than many other fibres. That is why it is a good idea to wash gently and avoid wringing the socks out hard. Press the water out between your hands instead and let them dry in peace.

Shrunk or just slack

Sometimes the sock feels smaller, but it has actually gone slack or lost its shape. When the elastic is worn, the sock sits differently and can seem too small at the heel. Try pulling the fabric gently while it is damp and shape it back on a flat surface. It does not always work.

What you can do afterwards

If the sock has shrunk, you can wet it again, pull it gently into shape and let it dry flat. It may help a little, but not always fully. Be realistic, and choose a size up next time if you often find that socks become too tight.

Look after the rest of your clothes

The same rules apply to the rest of your clothes. Bamboo boxer briefs and other knitted clothing do best with gentle washing and air instead of hot drying. Check the label and sort the wash, so zips and thick fabrics do not wear on the soft things in the same machine.

How to keep socks in shape

Wash at a low temperature, use a gentle programme, turn the socks inside out and let them dry in the air. That is the whole recipe for bamboo socks for men that last. The same care helps your bamboo T-shirts for men. If you follow the label, clothes last longer and you buy less new.

Frequently asked questions

Can shrunken socks get bigger again?

Sometimes you can gently pull them into shape while damp and let them dry flat. It does not always work, so prevent it by washing gently.

Can socks go in the tumble dryer?

The label will say. Preferably choose a gentle programme with low heat, or let the socks air dry, so they keep their size for longer.

What temperature should I wash at?

Follow the temperature on the label in the sock and choose low rather than high. A low temperature and a gentle programme are easier on the fibres and keep the fit.
